Brocade dual path, short and long on DCX 8510 backbone

  • 1.  Brocade dual path, short and long on DCX 8510 backbone

    Posted 10-30-2013 10:08 AM

    Hi Guys,  I'm pretty new to the SAN fabric world, so please forgive me if I'm not clear on what I am trying to accomplish.

    We have 4 DCX 8510.

    2 dcx at primary site

    2 dcx at secondary site

    The previous SAN guy already configure the dwdm settings on the 4 of the ports, but only 2 of them are working correctly when I go plug int the fc cable.

    For trouble shooting purpose, I swap out the fc cables on the ports and still only 1 path is working, the other port status shows in_sync but the health is offline and on the other end it shows no_light offline...  so I hope you guys can help me, I tried goggling it but can't find anything on it.

    Don't want to be rude but if you search the way you explain I'm not surprised you didn't find anything.

    I mean

    -no schematics

    -no info on dwdm gear used (brandactive/passive)

    -no info on which to cables you swapped between what actually?

    -what SFP's

    -Distance

    -ISL settings

    Please provide a description of you issue with most detail you are allowed to do.

    first at all, you should identify how the WDM are configures, SFP type, Speed Settings,...

    if the WDM is correct configured, is probable on DCX side, you have wrong SFP or wrong Port Settings.

    command sfpshow give the output SFP details, with portcfgshow you get detail son working and no-working port

    Try please to collect more info and post here.

    Would you like me to post the same info for the other dcx at our primary site?

    Hi,

    any idea on the WDM type, module types ? A picture perhaps?
